Paulson, 47, introduced George to her 4.1 million Instagram followers on Thursday, sharing an adorable photo of him sitting on a sofa as he basked in the sun.
The pair’s pet adoption experience adds to the many memories they have made since meeting on the set of the 1999 series Jack & Jill.
Paulson was even in the delivery room when Peet first became a mom. “It was very wild, and very, very poignant,” the actress said of the birth of Peet’s daughter Frances Pen Friedman. “And now she’s a 15-year-old person walking around.”
Peet added: “I get street cred for being her friend, from my daughter.”
